A007 A new boundary-element-based singularity removal approach for geoelectric forward solver Summary 1 We present a new singularity removal technique for 3D finite-element forward calculations of the geoelectric equations in the presence of significant topography. The technique which is based on the Trefftz boundary-element method (TBEM) allows the singular potential to be calculated numerically and subtracted from the finite-element equations. A numerical experiment demonstrates that the technique is accurate and computationally very efficient. Introduction During the past few decades much effort has been put into the development of numerical solutions of the 3D geoelectrical forward problem. Many solutions found in
